Listening to Zhao Yu's words, Song Qing couldn't help but smile and nodded.

"Yes, this is also a bit similar to Qianli Transsound, but this is simple, as long as two people have mobile phones, and then enter each other's numbers to talk to each other immediately, and there is no time limit."

"Of course, there is also a kind of video call, that is, you can see each other from your mobile phone from thousands of miles away, but the premise is that everyone is in this time and space, because you have to be connected to the Internet to use it."

"Can you still see each other thousands of miles away? This video call is also magical. ”

He wants to buy one, so that no matter where he is in the future, he can see his mother for the first time. Talking about how much silver does the one called the mobile phone cost?

Or gold?

Zhao Yu listened to it with relish, and he couldn't wait to buy a mobile phone to practice the operation.

"Yes, after all, technology has advanced in the era of development, and many things have been invented. These will be able to read on your own after you can learn simplified Chinese characters yourself. When the time comes, you can just go to the library and read it yourself, and all the books in it will be free to read. ”

Zhao Cheng raised his eyebrows, although he didn't understand Song Qing's words, but he also understood that the library should be a library pavilion.

It's just that now it's so good, and the books in the library can be borrowed for free, and sure enough, the times are different.

glanced up at Song Qing, although he didn't quite understand why Song Qing was not from the same time and space as him.

But no matter what, Zhao Cheng was very fortunate to come to her world at this time to reunite with her again, allowing him to learn more about her and the world she lived in.

"And in this day and age, people have now practiced the freedom to marry, and the practice is even more monogamous."

"Monogamy? That's pretty good. Zhao Cheng nodded lightly after hearing this.

In the past, the backyard of those ministers' mansions was not chaotic to death, and there were fewer wives and four concubines, and some even seventeen or eighteen were normal.

Either the concubine poisoned the lady to ascend to the throne, or the lady poisoned the concubine or the concubine's child.

In short, the intrigue is very chaotic, and there are always so many unborn children or a few lives lost in every backyard.

"Ancient people, I'm afraid there should be few people who think like you. After all, you are a rare dedicated man in history. ”

Zhao Cheng raised his head and glanced at Song Qing lightly.

Isn't his wife her?

Song glanced at Zhao Cheng lightly and continued to speak: "Now our era has paid attention to equality between men and women."

"Men can go out to work, women can do it, and the main thing is that there has been no emperor for more than a hundred years now. Now there is only a president, and it is changed every three years, and the people of the whole country vote for ......"

Song Qing's voice was gushing, but it was very similar to the appearance of the teaching director standing on the podium when she was studying.

At this moment, she finally understood the feeling of the dean of education at that time.

I want my students to be able to understand what they're saying.

Zhao Cheng and his son listened to Song Qing's explanation while staring at the computer screen, and from beginning to end, they only felt that what they saw had subverted their previous cognition, and even felt that the three views had been refreshed.

Look at the images on the computer screen.

Influenced the development from ancient times to the present, I only felt a little dizzy in my brain and eyes when I looked at it all the way.

It turns out that the world has become strange to them now.

If it weren't for the high IQ of their father and son, I'm afraid they wouldn't be able to understand or understand it at all, after all, this is not a little advanced.

It's a full 1,400 years......
